Description

Technical Field

[0001] This invention belongs to the field of conductive contact product manufacturing, and specifically relates to an in-mold welding device for silver contacts. Background Technology

[0002] A contact point refers to the junction or contact surface between two conductors through which current can pass. Because metal conductor terminals are prone to instantaneous heating and sparks at the moment of contact, their contact points are prone to oxidation and electrolysis during high-frequency use. Therefore, the contact points are enlarged and thickened, or made of polymer metal. Thus, this contact point made of polymer metal, or a point made of the same material that is enlarged and thickened, is called a silver contact point.

[0003] Traditional electrical contact welding requires stamping the strip into individual pieces outside the mold before pouring them into an automatic welding machine. This process involves unnecessary material handling and personnel input, and introduces instability. The stamped individual pieces are left in a free state before being arranged in a regular pattern for welding, resulting in low welding efficiency and failing to meet the requirements of automated welding.

[0004] In-mold welding involves directly and continuously welding silver contacts onto the strip, followed by stamping to form the part. Compared to traditional processes, this method offers higher welding efficiency. The silver contacts are as follows: Figure 1 The small circular structure shown is relatively small in size and needs to be accurately transported to the welding station for welding in automated in-mold welding production. In the prior art, patent CN201811636692.3 discloses an in-mold welding silver point gripping device, which uses a specific silver point gripping mechanism to grip the silver contacts and then perform continuous welding on the material strip. This device has high precision requirements and is easily affected by the environment, such as vibration, which can easily cause the silver contacts gripped by the silver point gripping mechanism to fall off. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an in-mold welding device for silver contacts.

[0006] The technical solution adopted in this invention is as follows: an in-mold welding device for silver contacts, comprising a contact feeding module, a welding module, and a driving module, wherein the contact feeding module is used to feed silver contacts to the welding module; the welding module is used to weld the silver contacts one by one onto the strip; and the driving module is used for the welding module to perform welding.

[0007] The welding module includes a main body, a conveying track, an upper welding component, and a lower welding component. The conveying track is arranged along the X-axis and fixedly mounted on the main body. The upper or lower welding component is fixedly connected to the main body and is movable relative to the main body, allowing the upper and lower welding components to be in a welding state and a separate feeding state. The inlet end of the conveying track corresponds to the position of the contact feeding module, and its outlet end corresponds to the position of the lower welding component in the separate feeding state. The conveying track is hollow and has a limiting conveying cavity adapted to the shape of the silver contact.

[0008] The drive module switches between welding state and separation loading state by driving the lower welding component or the upper welding component to move relative to the main body.

[0009] The contact feeding module includes a mounting base, a frequency-vibration base fixed on the mounting base, a vibrating plate fixed on the frequency-vibration base, and a feeding guide rail connected to the output port of the vibrating plate. Further, the mounting base includes a bottom bracket and a fixed guide rail located below the bottom bracket. The fixed guide rail is arranged along the Y-axis direction, and the bottom of the bottom bracket has a guide rail groove that engages and slides with the fixed guide rail. The frequency-vibration base is fixed above the bottom bracket.

[0010] The upper welding assembly and the lower welding assembly are rotatably connected by a connecting assembly. The connecting assembly is located at one end of the main body near the contact feeding module. The connecting assembly includes an upper connecting seat fixedly connected to the upper welding assembly and a lower connecting seat fixedly connected to the lower welding assembly. The upper connecting seat has a through slot for the conveyor track to pass through. The upper connecting seat has protrusions on both sides forming hinge shafts. The lower connecting seat has connecting plates located on both sides of the upper connecting seat. The connecting plates have hinge holes for the hinge shafts to pass through, and rolling bearings are installed within the hinge holes. The main body has a central section for the conveyor track to pass through. The upper welding assembly is fixedly connected above the main body and protrudes downward at the end of the main body away from the contact feeding module to form the upper welding end. The lower welding assembly is located below the main body and protrudes upward at the end of the main body away from the contact feeding module to form the lower welding end. The upper welding end and the lower welding end are positioned opposite each other so that the lower welding end in the welding state is close to the upper welding end to form a welding distance for welding the material strip and the silver contact. The lower welding end in the separation feeding state is positioned opposite the outlet end of the conveyor track so that the silver contact moves directly above the lower welding end after leaving the outlet end of the conveyor track.

[0011] Heat insulation components are provided between the main body base and the upper welding assembly, as well as between the upper connecting base and the upper welding assembly.

[0012] A T-shaped limiting block is fixedly connected below the main body base. The lower welding assembly is provided with a through groove. The T-shaped limiting block passes through the through groove and forms a lower limiting effect on the lower welding assembly. A heat insulation component is provided at the lower end of the lower welding assembly corresponding to the position of the T-shaped limiting block.

[0013] The main body has a slot in the middle, and an air blowing component is installed in the slot. The conveying track is provided with an air blowing port for the air blowing component to blow air into the limiting conveying cavity. The air blowing component is used to blow air into the conveying track to form a driving force for the silver contact to move along the conveying track toward the outlet end.

[0014] The drive module includes a fixed base, a sliding rod, a top block, and an L-shaped rocker. The upper end of the fixed base is provided with a groove for the sliding rod to extend into, and the lower end of the fixed base is provided with a movable groove for the L-shaped rocker to extend into. The sliding rod extends into the groove, with its top located above the fixed base and connected to a limiting top cover, and its bottom extending into the movable groove and fixedly connected to the top block. The middle bend of the L-shaped rocker is located in the movable groove and is hinged to the fixed base. The upper end of the L-shaped rocker in the movable groove abuts against the top block. Under the action of the up and down movement of the sliding rod, the L-shaped rocker rotates around the hinge axis. The outer end of the L-shaped rocker outside the movable groove is located below the lower welding assembly.

[0015] The L-shaped rocker is rotatably connected to a roller at its upper end within the movable groove, and the top block has a curved surface that cooperates with the roller.

[0016] A driving component is located below the lower welding assembly. The outer end of the L-shaped rocker plate, located outside the movable groove, is below the driving component. The driving component drives the lower welding assembly. The driving component includes a pressure rod, a limiting rod fixedly connected to the upper end of the pressure rod, and a lower abutment ring, a compression spring, and an upper abutment ring sequentially sleeved around the pressure rod from bottom to top. The outer wall of the pressure rod has a threaded portion. The lower abutment ring is threadedly connected to the pressure rod. The upper end of the upper abutment ring abuts against the limiting rod and simultaneously abuts against the lower welding assembly. A limiting sleeve is fixedly provided at the lower end of the main body. The lower welding assembly has a through groove, through which the limiting rod extends into the limiting sleeve. The limiting rod and the limiting sleeve cooperate to limit the limiting rod to slide only in the Z-axis direction. At the same time, the limiting rod has a strip-shaped limiting groove along the Z-axis direction, and the limiting sleeve has a limiting pin through hole. The limiting pin passes through the limiting pin through hole and the strip-shaped limiting groove to limit the sliding stroke of the limiting rod in the Z-axis direction. The outer end of the L-shaped rocker plate outside the movable groove is fixed with an anti-collision pad. The L-shaped rocker plate acts on the pressure rod through the anti-collision pad, and a second insulating gasket is provided between the anti-collision pad and the L-shaped rocker plate.

[0017] The upper end of the fixed base is connected to an upper connecting cross seat. The upper connecting cross seat is provided with a strip-shaped connecting stepped groove arranged along the X-axis. Two guide strips with a certain distance between them are fixed below the upper connecting cross seat. The upper end of the upper welding assembly is fixedly connected to a fine-tuning assembly. The upper end of the fine-tuning assembly has a T-shaped guide block. The T-shaped guide block can slide and be limited between the two guide strips along the X-axis. The T-shaped guide block is provided with a first connecting screw hole. The strip-shaped connecting stepped groove and the first connecting screw hole are connected in sequence by fastening bolts so that the fine-tuning assembly is fixedly connected to the lower part of the upper connecting cross seat in an adjustable position.

[0018] The beneficial effects of the present invention are as follows: The silver contacts of the present invention are transported to the lower welding assembly via a conveyor track and then welded, which can improve production efficiency, reduce production costs, and improve welding quality.

[0040] An in-mold welding device for silver contacts, such as Figure 2 As shown, it includes a contact feeding module 100, a welding module 200, and a drive module 300.

[0041] The contact feeding module 100 is used to feed silver contacts to the welding module 200;

[0042] The welding module 200 is used to weld the silver contacts one by one onto the strip;

[0043] The drive module 300 is used by the welding module 200 for welding.

[0044] The structure of the contact feeding module 100 is as follows: Figure 3 As shown, the system includes a mounting base, a frequency-vibration base 110 fixed on the mounting base, a vibrating plate 120 fixed on the frequency-vibration base 110, and a feeding guide rail 130 connected to the output port of the vibrating plate 120. Further, the mounting base includes a bottom bracket 111 and a fixed guide rail 112 located below the bottom bracket 111. The fixed guide rail 112 is arranged along the Y-axis direction. The bottom of the bottom bracket 111 has a guide rail groove that engages and slides with the fixed guide rail 112. The frequency-vibration base is fixed above the bottom bracket 111. The mounting base allows the position of the output end of the feeding guide rail 130 along the Y-axis direction to be adjustable.

[0045] Among them, such as Figure 4 As shown, the welding module 200 includes a main body 210, a conveying track 220, an upper welding component 230, and a lower welding component 240. The conveying track 220 is arranged along the X-axis and fixedly mounted on the main body 210. The upper welding component 230 or the lower welding component 240 is fixedly connected to the main body 210, and the lower welding component 240 or the upper welding component 230 is movable relative to the main body 210 so that the upper welding component 230 and the lower welding component 240 have a welding state and a separate feeding state. The inlet end of the conveying track 220 corresponds to the position of the contact feeding module 100, and its outlet end corresponds to the position of the lower welding component 240 in the separate feeding state.

[0046] The drive module 300 drives the lower welding component 240 or the upper welding component 230 to move relative to the main body 210, thereby switching the upper welding component 230 and the lower welding component 240 between welding state and separation feeding state. The conveying track 220 is hollow and has a limiting conveying cavity adapted to the shape of the silver contact.

[0047] In the welding module 200, the upper welding component 230 is fixedly connected to the main body 210 and the lower welding component 240 is movable relative to the main body 210. The driving module 300 is used to drive the lower welding component 240 to move relative to the main body 210 so that the upper welding component 230 and the lower welding component 240 switch between welding state and separation feeding state.

[0048] Specifically, such as Figure 4-6As shown, the upper welding assembly 230 and the lower welding assembly 240 are rotatably connected by a connecting assembly, which is located at one end of the main body 210 near the contact feeding module 100.

The main body 210 has a through slot in the middle for the conveying track 220 to pass through, and the upper welding assembly 230 is fixedly connected to the main body 210. The upper welding end 231 is formed by protruding downward at the end of the main body 210 away from the contact feeding module 100. The lower welding component 240 is set below the main body 210 and protrudes upward at the end of the main body 210 away from the contact feeding module 100 to form the lower welding end 241. The upper welding end 231 and the lower welding end 241 are positioned opposite each other so that the lower welding end 241 in the welding state is close to the upper welding end 231 to form a welding distance for welding the material strip and the silver contact. The lower welding end 241 in the separation feeding state is positioned corresponding to the outlet end of the conveying track 220 so that the silver contact moves directly above the lower welding end 241 after leaving the outlet end of the conveying track 220.

A first insulating gasket 290 is provided between the fine-tuning component 260 and the upper welding component 230. The fine-tuning component 260, the first insulating gasket 290, and the upper welding component 230 are connected and fastened by fastening bolts in sequence.

[0059] The welding process in this embodiment is as follows:

[0060] 1. The feeding module 100, via the fixed guide rail 112 under the bottom bracket 111, positions the vibratory feeder 120 in a precise fixed position, ensuring that the outlet of the feeding guide rail 130 on the vibratory feeder 120 aligns with the inlet end of the conveying track 220 of the welding module. This allows the contacts to pass through the outlet of the feeding guide rail 130 and the inlet end of the conveying track 220 without resistance. The movement of the contacts within the plate is adjusted by the vibration of the frequency-vibration base, achieving the purpose of feeding.

[0061] 2. Drive module 200: The punch press drives the slide bar 320 to move up and down. Force is transmitted to the pressure rod 271 via the top block 330 on the slide bar 320 and the roller 341 on the L-shaped rocker plate 340, causing the pressure rod 271 to move up and down. The continuous up and down movement of the punch press continuously drives the welding process, completing the entire operation.

[0062] III. Welding Module 200: When the slide bar 320 moves downward, it causes the L-shaped rocker 340 to rotate. The L-shaped rocker 340 then contacts the pressure rod 271 of the welding device, causing it to move. The compression spring 274, located on the pressure rod 271 of the welding device, then presses upward, causing the upper abutment ring 275 to push against the lower welding assembly 240, which moves upward. After the contact point enters the welding electrode weld groove position via the guide rail, the lower welding assembly 240 moves upward through the above actions, bringing the contact point into contact with the material strip and the upper welding assembly 230 to complete the welding.

[0063] IV. By repeating steps one through three above, fully automated welding production can eventually be achieved.

[0064] Those skilled in the art will understand that all or part of the steps in the methods of the above embodiments can be implemented by a program instructing related hardware. The program can be stored in a computer-readable storage medium, such as ROM / RAM, disk, optical disk, etc.

[0065] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
